Anti-Termites Properties of Liquid Smoke from Bintangur Wood

Abstract

Wood and wood-based products are very vulnerable to termite attacks. One of the methods to control termite attacks is using chemical insecticide. However, the use of chemical insecticide is considered a negative effect on the environment. The aim of this research was to determine the anti-termite properties of liquid smoke against Coptotermes curvignathus Holmgren. The liquid smoke derived from bintangur wood pyrolysis at 370°C, 400°C, and 430°C was assessed as an anti-termite activity. Anti-termite activities against C. curvignathus were conducted by using liquid smoke with the concentration of 2%, 4%, 6%, and 8% (v/v). Simple linear regression was used to measure the effect of liquid smoke concentration against C. curvignathus. The results showed that the liquid smoke concentration of 6% and 8% at the three pyrolysis temperatures effectively controlled the subterranean termite's attack and resulted in 100% termites mortality. The chemical content of bintangur wood vinegar has contained phenol (1.23–1.65%) and acid (4.33–6.68%). Keywords: acid content, antitermitic activity, bintangur wood, phenol content, wood vinegar

“…Termites are sensitive insects and their activities are easily disturbed, so it is necessary to condition the termite colony before testing. In addition, Oramahi et al (2021) stated subterranean termites Coptotermes curvignathus are termites that require a moist place to live, the ideal temperature and humidity conditions such as their natural habitat. Therefore during the test the temperature should be measured, if it is too high and the humidity is too low, it can trigger an increase in the mortality of subterranean termites.…”
